Dynabeads Products & Technology

Applied Biosystems™ Dynabeads™ and Invitrogen™ Dynabeads™ magnetic separation is gentle and tube-based. No columns or centrifugations are necessary. The true uniformity of bead size, shape and surface area provides optimal accessibility and rapid liquid-phase reaction kinetics. You can reduce variability and get more reliable and reproducible results for your purifications and your analyses.

Dynabeads technology for magnetic bead separation

Magnetic particles (Figure 1) from alternative suppliers often have a random size range and surface area that could compromise the reproducibility of your results.The tightly controlled Dynabeads production processes give uniform spherical beads, with highly defined and consistent product characteristics. By reducing particle variability, you get more reliable and reproducible results.

The level of reproducibility within and between batches of Dynabeads is quite unique. The same surface area is offered for each experiment, ensuring the best efficacy and reproducibility for your analyses.

Characteristics of Dynabeads

Dynabeads are superparamagnetic particles, meaning that they exhibit magnetic properties when placed in a magnetic field with no residual magnetism once removed from the magnetic field
